Hardware upgrade & FC3?

I have FC3 installed at the moment on a lucky star KT100 motherboard,
with 512SD RAM and AMD Athlon 1.4GHz proccessor. I just got a good deal
on a brand new Soltek motherboard, 512 DDR RAM and AMD Athlon 2.4GHz
processor. My question is, how will fedora handle this hardware upgrade,
first of all will it boot? The HDD an all other other hardware will
remain as they are.

I just don't want to try it before I ask someone.. don't want to do a
new install if not nessecary.
